The server won\'t accept any parameters in a request URL, so I need to remove all the extra parameters in the URL and of course I can\'t control the server.
jQuery:<
JSONP requires a callback as part of the URL. I would guess based on the description that the server you are accessing does not support JSONP.
jQuery adds a script tag to your document, which when added runs the API request, the response calls the callback function in your code (this is simplifying it).
You can take a look at Wikipedia if you want a more accurate description. http://en.wikipedia.org/wiki/JSONP#How_it_works
